Versiunea originală de Lukasz Kopciuch
ULTIAIR este o familie de access point-uri profesionale proiectate pentru utilizarea îndelungată în exterior. Integrarea unui emiţător şi a unei antene într-o singură carcasă permite instalatorului o montare simplă şi rapidă fără acţiuni suplimentare.
ULTIAIR has been designed for creating efficient wireless IP CCTV and ISP networks.
ULTIAIR devices are characterized by short delays and high throughput. They can be managed via WinBox utility or telnet. They operate in unlicensed 5GHz band - no special permissions are needed. The devices can operate as client or base stations.
The RouterBoard with Mikrotik system has been put in outdoor housing of IP 66 class, which guarantees full protection against adverse weather conditions and corrosive environments (industry).
Main features:
  • Flexible configuration;
  • Possibility of creating advanced network systems;
  • Efficient data transmission;
  • Weather-resistant housing (IP 66);
  • Quick configuration of Access Point, Bridge, and HOTSPOT modes;
  • Easy installation.
WLANs based on the devices allow:
  • get wireless access to the LAN in home, office, business etc.
  • organize wireless access to the Internet (public hot-spots) in various public spaces, hotels, clubs, restaurants, cafes etc.
  • create wireless point-to-point links (bridging LANs, telemetry, remote control, remote monitoring),
  • provide Internet access via WLAN,
  • ensure uninterrupted data transmission by creating back-up links (for existing cable connections).

Un mare avantaj al echipamentelor ULTIAIR este versatilitatea lor.
ULTIAIR devices are perfect for creating effective systems of city monitoring. ULTIAIR family allows to build both the backbones of the systems and wireless access networks. The unique versatility of the devices is based on the implemented Linux software that allows different applications, from simple point-to-point links, indispensable in extensive IP video surveillance systems, to very sophisticated systems of data transmission.

The difference consists in the number of supported protocols and modes of work. It is shown in the table above (License levels).  

Higher gain enables transmission over longer distance

The exact angles are available in specifications of every ULTIAIR device.

The users (1) connect to the station (2) that enables them to get access to the Internet.
Wireless video surveillance system
CCTV systems based on IP technology, equipped with IP cameras, become more and more popular. It is due to simple installation and configuration of the systems. Very often the distances between buildings are too large for using wired links (FTP cable). A simple solution is wireless transmission based on ULTIAIR devices.

The devices are ideal for transmitting images from megapixel cameras
The resolution of analog video is limited by TV standards (PAL, NTSC) - for PAL the maximum is 720 x 576 pixels. Such limits do not apply to IP systems equipped with megapixel cameras. Their images can be enlarged ten or more times (depends on the actual resolution), still preserving details needed e.g. for identification purposes.
Many experts think that megapixel cameras will soon replace PTZ devices, especially in city video surveillance systems. ULTIAIR equipment, with throughput up to 54 Mb/s, perfectly solves the problem of data transmission. Wireless solutions can considerably lower the costs of implementing these modern systems. They eliminate the need of building cable infrastructure (e.g. the cables from the cameras to the monitoring center, even several kilometers long). The cameras are connected to ULTIAIR devices, the monitoring center - also equipped with a ULTIAIR device - receives the data wirelessly.
Both for the transmission of video stream and PTZ commands there can be used access points integrated with antennas, powered with the use of PoE technology. There may be employed sector antennas that will create easily manageable sectors.

ULTISYSTEM - IP CCTV system for cities

The diagram below presents a solution based on ULTISYSTEM software, ULTIAIR access points and ACTi IP cameras. The system can be expanded by using different modes of operation of the ULTIAIR devices (to be continued in next issues). The system can utilize some cameras of local monitoring systems based on ULTIMAX DVRs and analog cameras.
